The same company rolled out F-class gas turbine capable of generating 50 MW.

E class heavy duty Gas turbine localization = 100%

F class heavy duty Gas turbine localization = 100%

H class heavy duty gas turbine is a real deal and only 3 countries masters in this technology. USA , Germany and Japan.

Dongfang Steam Turbine recently announced first H class heavy duty gas turbine 'M701J' being made in mainland a milestone but localization still at 70%. some core hot parts are imported. by 2024 China will conquer H class heavy duty gas turbine as well.

China become the only 4th country to produce H class heavy duty gas turbine with some hot parts imported. still a huge leap

What about G and J-classes? Are G and H the same classes?

This was 2016 news，Dongfang signed tech transfer agreement with Mitsubishi，for F class M701F5 and H class M701J

So it took Dongfang 8 years to digest and localize the technology. Don't know the domestic rate of this M701J，but since the news didn't mention “100% domestic”，I'd assume it's not 100% domestic.

heavy duty gas turbines are crown jewel of heavy industries. so yeah it took Dongfang 8 years to localize much of H class technology but M701J still not 100 percent domestic. some hot components imported. it is matter of time until China will produce full indigenous H class heavy duty gas turbine.

Firstly, I ain't sure of how a large passenger aircraft powered by WS-20 would be like. Besides, aren't there CJ-1000A and CJ-2000 that would eventually power future Chinese civilian airliners?

I think WS-20 was the evolved SF-A which was the domestic option/alternative/backup for C-919 proposed by Shenyang Liming. CJ-1000A is the JV option that is thought to be based on the latest tech.

Therefore, I don't really understand the need for WS-20 on civilian platforms, unless the sudden export ban imposed on the LEAP-1C engines for the C919 necessitate introducing WS-20 to the civilian airliner as a stopgap measure.

As a backup, WS-20 isn't needed if CJ-1000A is ready on schedule and LEAP-1C is secured. Otherwise it is needed. There is no reason to stop evolving WS-20 for civilian application regardless the other options. It is better to be prepared than relying on the "friendliness" of GE for LEAP-1C, or other western partners of CJ-1000A. The preparedness reduces the incentive of west weaponizing the engines and keep them "friendly".
